IMPROVEMENT IN WATER-METERS.

Specification forming part of Letters Patent No. 47,866, dated May 23,1865.

will enable those skilled in the art to make and use the same, referencebeing bad to the accompanying drawings,forniing part of thisspecification, in which-- Figure 1 is a sectional elevation of awatermeter constructed after my inv ention,taken on theline m of Fig. 3,the side being broken away ih part to show the location of the gearingor wheel-work by which motion is transmitted to the indices of themeter. Fig. 2 isa plan view of my meter. Fig. 3 isa plan view of ahorizontal section of the meter below the plate 1/), showing thewater-chamber C. Fig. 4 is a detailed View of the gate h.

Similar letters of reference indicate corresponding parts.

This invention consists in adapting the principles of construction ofthe ordinary central discharge water-wheel .to the purposes of awater-meter.-

A represents the water-meter, composed of the chamber B, which containsthe wheelwork and indices and dials for recording the work done or thewater passed through the meter, and of the water-chamber O, the twochambers being separated by a metallic diaphragm, p, perforated at itscenter to permit the passage of the shaft I) from the waterchamber tothe index-chamber. The two chambers are secured together by means oftheir flanges c and], which are bolted together .by screw-bolts g, thediaphragm 1) being socured between them. The shaft 1) is properlystepped and secured according to the art of the machinist, its lower endbeing supported upon the cross-piece k at the mouth of the centraldischarge-pipe, b.

- The inductionpipe of the meter is designated by the letter d, and ithasa screw-thread out upon its exterior to enable me to connect theinlet-passage 0 tothe point in its side.

A gate h, is set vertically in the inlet passage 0 along its inner side,being secured therein by means of a fulcrum-pin, i, which passes throughthe flanges e and f, the diaphragm p,

and a flange, j, which projects from the. head of the gate at rightangles thereto. The gatcj his to be set by means of its fulcrum i at anydesired angle in the inlet-passage 0, the measure of the capacity of themeter being altered by the contraction and enlargement of the inlet bythis means. The passage of the water through the water-chamber will turnthe vanes a and their shaft D, and thereby V the wheel-work in theindex-chamber will be operated so as to cause the amount of work or thenumber of revolutions of the shaft to be recorded in the ordinarymanner, the water being discharged through the central opening, 11

' The graduation of the wheel-work with the capacity of theinlet-passage O and of the water-chain her and the graduation of theinlet-passage itself by means of the gate are to be made in the usualway, and I have not thought it necessary to ascertain them for thepurposes of this application, as these results are not embraced in thescope of my invention.

I claim as new and desire to secure by Letters Patent- The combinationof thewings a a, shaft D, rate h, and inlet-passage 0, all arranged toiperate substantially as specified.
